Embodiment Construction

[0051] figure 1 is a structural schematic diagram of a transmission according to an embodiment of the present invention. The present invention provides a four-clutch serial transmission, in one embodiment, as figure 1As shown, the transmission includes input shaft one IS1 and input shaft two IS2 coaxially sleeved, first clutch C1, second clutch C2, driving gear set one, driving gear set two, output shaft one OS1, driven gear set one , driven gear set two, coaxially sleeved output shaft two OS2 and output shaft three OS3, driven gear set three, driven gear set four, third clutch C3, fourth clutch C4 and differential DIFF. The first input shaft IS1 is connected to the power source through the first clutch C1, and the second input shaft IS2 is connected to the power source through the second clutch C2. The power source here can be an engine, a motor or other commonly used power sources for vehicles. One drive gear set is set on the first input shaft IS1, and the second drive ge...

Abstract

The invention provides a four-clutch tandem type transmission and a power assembly, and belongs to the field of vehicles. The transmission comprises an input shaft I, an input shaft II, a driving gearset I, a driving gear set II, an output shaft I, a driven gear set I, a driven gear set II, an output shaft II, an output shaft III, a driven gear set III, and a driven gear set IV, wherein the inputshaft I and the input shaft II are coaxially arranged in a sleeving manner and are connected to a power source through a first clutch and a second clutch; the driving gear set I and the driving gearset II are respectively arranged on the input shaft 1 and the input shaft 2 in a sleeving manner; the driven gear set I comprises a plurality of gears which are engaged with gears of the driving gearset I and the driving gear set II; the driven gear set II is arranged on the output shaft I in a sleeving manner; the output shaft II and the output shaft III are coaxially arranged in a sleeving manner and are connected to a differential mechanism through a third clutch and a fourth clutch; the driven gear set III comprises a plurality of gears which are engaged with a part of gears of the drivengear set II; and the driven gear set IV comprises a plurality of gears which are arranged on the output shaft III in a sleeving, separation and reunion manner, and are engaged with other gears of thedriven gear set II. The four-clutch tandem type transmission can increase the number of gears of the transmission without increasing the number of the gears.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a four-clutch serial transmission and a power assembly. Background technique [0002] The speed of the car is constantly changing during driving, which requires the speed and torque of the driving power to also change continuously, and the car engine can only work at a certain speed and torque, so a transmission is needed to change the speed and torque output by the engine. At present, the vehicle transmission mainly consists of manual transmission (MT), electromechanical automatic transmission (AMT), hydraulic automatic transmission (AT), continuously variable transmission (CVT), and dual clutch transmission (DCT). repeat. Among them, the dual-clutch transmission is an upgraded version of the manual transmission, which realizes shifting without power interruption through the combination of dual-clutches in turns and the pre-engagement of gears. [0003] Because the current dual clutch ...
